- venting the same.

Another object of my invention is to provide in a system, of the character described, the fewest number offittings and provide such fittings that are so constructed that they may be roughly handled without fear of damage; that may be quickly and economically assembled and installed in the system and that are of minimum, weight consistent with good construction.

Other and further objects of my invention will become apparent to those skilledin the art from the following description taken in connection with the accompanying drawings; wherein, I

Figure 1 shows an elevation of a fragment of my sys uem and fittings constituting a part of the same. Fig. 2 is a cross-section taken on line 2-2 of Fig. 1. Fig. 3 is a central longitudinal section of Fig. 1. I Fig. i is a fragment of an elevation of av multiple-duet fitting, showing a single terminal flange for all of the ducts. Fig. 5 is a section of a lower portion of Fig. 2, taken on line 55 thereof;

ig. 6 is a plan view of Fig. 4, looking at the bottom end.

In all of the views the same reference characters indicate the same parts.

In the drawings, illustrating the system, I have shown fittings, constituting partof'the system, which are made in accordance with my invention. l

The system includes-two parallel, vertical and continuous stacks composed of a plurality of sections of pipe, one of which I shall designate the waste or drainage stack and the other the vent stack. At each floor special fittings are connected in the lines of these stacks, consisting of a combination fitting comprising a plurality of parallel reventducts and a section of the vent stack made in an integral whole therewith, and a special sanitary T providing double, non-communi- Letters Patent.

eating passage ways, one for the material that may come down the Waste or drainage stack and the revent conduits and the passage way comprising a part or section of the vent stack. The latter it will be noticed, by reference to Fig. 5, goes around the former.

A is a pipe section of the soil stack, of which there may be one or more intermediate the respective floors of a building.

T is one of my special fittings comprising a part of my system of drainage-venting. It is a specially constructed sanitary T provided with a passage-way a, comprising a section of the vertical soil stack and communicating passage-ways, a, a" and a which lead from the vent ducts 1, 2 and 3 into the waste stack A.

B is a section of the vent stack contained in and as a part of the multiple-duct fitting or casting D. g

B isa section of the vent stack, made as an integral part of the fitting T, but the interior thereof does not communicate with said T, as shown clearly in cross section in Fig. 5.

The multiple-duct fitting D comprises a series of parallel ducts, made in a single casting, adjoining ducts being divided only by single Walls, and the lower end terminating in a single flange d, as shown in Fig. 6.

The ducts 1, 2 and 3 join the duct B, of

the fitting 1) near its top and afford separate passa 'eways for escaping gas, or the efiiux of air etween said point and theT. Duct 1 is a revent for a closet fixture which may be connected to the said stack A as by the socket C. Ducts 2 and 3 are revent conduits for other fixtures such as bath tubs, wash basins, etc., as shown in Fig. 1. Such fixtures may be connected to the socketed openings, t, t, 12 respectively. Other similar openings, such as t may be provided for other such fixtures.

It will be observed that the fitting D has a single flange d for the plurality of ducts 1, 2, 3 and B.

The T is provided with a single socket i for the accommodation of the flange cl.

To make the joints between the parts D and T the flange end (1 is inserted in the socket i and lead is compacted around the space within the t and the bodypart of D. The flange d will prevent the latter from being easily removed. Another socket i is provided in the upper end of theT fitting for the accommodation of the flanged end of the pipe A. Thus five pipes may be joined to the T fitting with very little more trouble or expense than when two pipes are so joined.

Fig. 3 represents a section of my system located near the top of the building where the top of the fitting D is connected into the soil stack A by means of a convenient fitting such as 13 At other or lower floors the stack is continued vertically and independently as at B Preferably one of the ducts of the fitting D, as the duct 2, is left withoutfitting attachment so that it may perform its revent function in any event.

The use and operation of my system is so obvious as to not require further and more specific reference thereto.

Having thus described my invention, what I claim and desire to secure by Letters Pat ent, of the United States, is;

1. In a system of the character described, having a main vent stack and a main waste stack, extending from floor to floor of a building, a multiple-duct fitting including a section of the main vent stack, a receiving T located in said main waste stack, having a single socket to accommodate said multiple duct fitting, and another socket for a single pipe constituting a section of the main waste stack.

2. A conduit iittin comprising in one integral united Whole a vent stack section, having a socket at one end, a plurality oi parallel, cylindrical, longitudinally-n11ited, vent ducts, shorter than the vent stack section and communicating therewith at one end and terminating in the same plane with said vent stack section at the other end, in a common plane and surrounded by a common flange encompassing all of said conduits.

3. In a system of the character described having a main vent stack and a main waste stack extending from floor to floor of a building, a fitting comprising a section of the vent stack and a plurality of parallel cylindrical, longitudinallyainited vent-ducts in a plane common to all, communicating at one end and flanged at the other end in emnbination with a sanitary T through which said waste and vent ducts pass, provided with a single socket for said fitting and a socket for said waste pipe.

4-. in a system of the character described, having main vent stack and a main waste stack extending from floor to floor ol a building, a sanitary? provided with non-communicating passage-ways, one oi said ]'):l.SSzif.T0 ways communicating with the vent stack and the other passageway communicating with the waste stack, and means whereby said stacks may be secured to said T.

5. In a system of the character described, having a main vent stack and a main waste stack extending from floor to floor of a building, a sanitary provided with a socket at one end and a flange at the other end for attachment to the aste stack, a common socket for a series of cylindrical vent duels in a common plane and a flanged extension for attachment to the vent stack a t the other end.

6. in a system of the character described. 1 ving a main vent stack and a main waste stack extending from door to iloor, a unitary fitting provided with non-connnunieatiilg cage ways, terminating in separate openings whereto said non-cominnnienting passageways may be attached respectively in communication with the vent and waste stacks.

In testin'iony whereof I hereunto set my hand in the presence of two witnesses. I
